Organization, automation, and efficiency are sort of the big differences. You can do all of that manually with scripts and cron, but generally these other systems make it easy to do.
I have no idea what you mean by "I think I will wait on btrfs until it is mainstream for a home computer". You can in fact use btrfs as the main file system in Ubuntu. The default format in Ubuntu creates two separate subvolumes (/ and /home), and if you install the apt-btrfs-snapshot package it will automatically snapshot your system before an apt upgrade. This means that weeks later, after creating tons of data, you can roll your system back to a point in time before you did an upgrade while preserving all the data created in the mean time. Of course none of this replaces a proper backup (the old 3-2-1 rule is still a good starting point).
